Ready-to-use ELISA kits are available for the detection of EBN2, an alias of the protein, potassium voltage-gated channel subfamily Q member 3. The official gene symbol is KCNQ3. The protein, with a mass of 96.7 kDa and length of 872 residues, is reported to be membrane-associated. It is a member of the Potassium channel family, KQT (TC 1.A.1.15) subfamily, Kv7.3/KCNQ3 sub-subfamily and may be known by other names, including: BFNC2, voltage-gated potassium channel subunit Kv7.3, potassium channel voltage-gated subfamily Q member 3, potassium channel voltage gated KQT-like subfamily Q member 3, potassium channel subunit alpha KvLQT3, and KV7.3.
